I'm interested in better understanding the ongoing geological processes that shape St. Louis and the Mississippi Valley region. So far, I've been looking into the history of seismicity in the region, focusing on the fascinating but little known history of the New Madrid earthquakes of 1811 and 1812 -- the most devastating earthquakes to have hit the US east of the Rockies. I've also been exploring how St. Louis and surrounding areas are dealing with the possibility of another earthquake occurring in the future. According to one article I read, one of the biggest uncertainties is what would happen to the heavily engineered Mississippi River in the case of another major tremblor. The shaking could break the levees, flooding wide areas along the river and creating cascading effects. The flow of the river might also reverse completely, as occurred during the New Madrid earthquakes.

On these possibilities and the lack of scientific consensus surrounding intraplate seismicity in this zone, see this article in The Atlantic.

On current efforts to create earthquake hazard maps in St. Louis, see this overview on the US Geological Survey site.

For a deeper dive into the history of the New Madrid earthquakes, see this book by historian of science Conevery Bolton Valencius. 

The main findings of the article are that the relationship between natural disasters and communicable diseases is not as much due to dead bodies or high trauma as it is to population displacement and a lack of preparredness of the local governing body for the disaster and the crowding of survivors that follows a disaster as this

This article has been referenced in a wide variety of emergency medicine journal articles, ranging from flood protocols, use of cell phones in disaster enviroments, earthquakes and medical complications, to the costs of disaster consequences. Many of the articles referencing this paper appear to go into greater depth for some of the epidemics and diseases that were touched on in the research article. These include hepatitis E, Leptospirosis, cholera, and tetanus.

This article shows how some communities that, in the opinion of the Disaster Accountability Project organization, are within an effective radius of a nuclear incident at Indian Point and have little or no emergency plan for this kind of event. This is primarily due to these communities not having the knowledge that they could be effected by an event of this nature if they are over 10 miles away from the plant. Also, many of the communities that said they had not undergone any studies in relation to the plant's effects on their own community or developed any emergency plans because they cannot without federal aid. These counties and towns are not well-enough informed and are lacking the funding from the government in order to provide for their own safety if a nuclear accident were to occur

Emergency response is addressed in a broad sense of the major risk factors associated with a natural disaster and epidemics. The main points they make are that preparedness, with a focus on availability of safe water and primary healthcare services, along with surveillance for the beginnings of an epidemic, are necessessay for a strong response to a disaster situation   

The National Regulatory Commission: Government agency responsible for public safety with regards to nuclear reactors and nuclear energy

Entergy: An integrated energy company that primarily deals with electric power production. Operators of the Indian Point Nuclear Power Plant

Disaster Accountability Project: Nonprofit organization that monitors disaster-response programs and acts as a watchdog for disaster response and preperation

The main methods that the authors appear to use are reported data from disasters that have happened around the globe, including numbers and types of infections, displacement and crowding data, and knowledge of the disaster incidents examined

The main point of the article is to report a conflict of opinions between the NRC and the Disaster Accountability Project on the safety of the communities surrounding the Indian Point Nuclear Power Plant. The NRC and the company running the plant, Entergy, state that those communities within a 10 mile radius are required to have emergency evacuation plans in place should a nuclear emergency occur; those outside this radius, however, are not at as large of risk. The nonprofit, however, cites the NRC's report on the Fukushima disaster, where it recommended the US citizens within 50 miles of the plant should evacuate the area, and suggests that communities within a 50 mile radius of Indian Point have specific nuclear emergency plans at hand and prepared for use. Entergy says that the radius "provides a robust safety margin", and the NRC replies to the Disaster Accountability Project's statement by saying that the incident at Fukushima is not comparable to any nuclear power cite in the US, due to the size and number of reactors in the Fukushima plant.

"The risk for commuicable disease transmission after disasters is associated primarily with the size and characteristics of the population displaced, specifically the proximity of safe water adn functioning latrines, the nutritional status of the displaced population, the level of immunuty to vaccine-preventable diseases..., and the access to healthcare services"

"...natural disasters (regardless of type) that do not result in population displacement are rarely associated with outbreaks"

"When death is directly due to the natural disaster, human remains do not pose a rise for outbreaks"
